Efficient computation of the genomic relationship matrix and other matrices used in single‐step evaluation

Journal of Animal Breeding and Genetics, 2011
SummaryGenomic evaluations can be calculated using a unified procedure that combines phenotypic, pedigree and genomic information. Implementation of such a procedure requires the inverse of the relationship matrix based on pedigree and genomic relationships.

Shrinkage estimation of the genomic relationship matrix can improve genomic estimated breeding values in the training set

Theoretical and Applied Genetics, 2015
We evaluated several methods for computing shrinkage estimates of the genomic relationship matrix and demonstrated their potential to enhance the reliability of genomic estimated breeding values of training set individuals. In genomic prediction in plant breeding, the training set constitutes a large fraction of the total number of genotypes assayed ...

Technical note: updating the inverse of the genomic relationship matrix.

Journal of animal science, 2013
A computing strategy to update the inverse of the genomic relationship matrix when new genotypes become available is described. It is shown that re-using results of previous computations can result in substantial reductions in computing time required.

A dimensionality-reduction genomic prediction method without direct inverse of the genomic relationship matrix for large genomic data

Plant Cell Reports, 2023
A new genomic prediction method (RHPP) was developed via combining randomized Haseman-Elston regression (RHE-reg), PCR based on genomic information of core population, and preconditioned conjugate gradient (PCG) algorithm. Computational efficiency is becoming a hot issue in the practical application of genomic prediction due to the large number of data

Improving genomic evaluation of Holstein cattle using a haplotype-based relationship matrix

2018
With the advent of high throughput genotyping technologies, interest has grown in using genomic information to estimate breeding values. Genomic selection, in which genetic markers across the whole genome are used to estimate breeding values of individuals, is routinely applied in dairy cattle breeding programs.
